The are 3 reasons for that:
- Some DNS servers still use previously cached records and not all traffic is filtered by SkyparkCDN. You need to wait.
- You didn't change your real IP to a new one after you enabled DDoS Protection. It means that a perpetrator knows it and attacks directly. You need to get new IP from your hosting.
- You didn't limit access to your server. Сontact your hosting provider or use a firewall to limit access to your server to all but our IP range and trusted IPs.
